AI Article Synopsis
- A study evaluated a new digital workflow for implant placement and immediate delivery of complete-arch prostheses in 10 patients, showing high success rates.
- Out of 60 implants placed, only one failed, leading to a cumulative success rate of 98.3% with no prosthetic complications reported.
- The results suggest that this dynamic navigation technique effectively streamlines the surgical process, potentially improving outcomes in dental implant procedures.
Article Abstract
Objective: To assess clinical and radiological performance of novel digital workflow integrating dynamic guided surgery, to streamline execution of implant placement, soft and bone tissue sculpturing, and immediate delivery of navigation guided complete-arch prosthesis.
Materials And Methods: This proof of concept prospective single cohort study investigated 10 consecutive patients (three males, seven females; mean age 62.5 ± 8.9 years; range, 48-75) requiring at least one complete-arch fixed dental prostheses (FDP) in both jaws, treated between January and August 2019. Primary outcomes were implant and prosthetic success rates, surgical and prosthetic complications. Secondary outcomes were marginal bone loss (MBL), implant stability quotient (ISQ), periodontal parameters (plaque and bleeding indexes).
Results: Sixty implants (32 NobelParallel TiUltra and 28 NobelActive TiUltra, Nobel Biocare) were placed and 14 complete-arch FDPs immediately loaded (mean follow-up 16.2 ± 1.7 months, 14-18). One implant failed and was immediately replaced. No other surgical or biological complications occurred, accounting for a cumulative success rate of 98.3%. No prosthetic complication occurred, leading to 100% prosthetic success rate. Mean ISQ at implant placement was 71 ± 2.8 (65-78). The mean MBL was -0.53 ± 0.28 mm (-0.22 to -1.12 mm). Plaque and bleeding scores were 14.4 ± 8.18 and 7.15 ± 4.4, respectively.
Conclusion: Within the limitations of this proof-of-concept dynamic navigation was effective to deliver in the planned coordinates both implants and prosthesis and guide bone and soft tissue sculpturing. Immediate loading of digitally prefabricated esthetically driven complete-arch FDP was facilitated, resulting in high implant and prosthetic success rates.
Clinical Significance: The investigated digital workflow integrating dynamic navigation may overcome the difficulties related to immediate positioning and loading of digitally prefabricated complete-arch FDP. The navigation guided soft and bone tissues sculpturing, associated to xenogeneic collagen matrix grafting, represented a predictable technique to achieve the digitally planned interface, reestablishing the mucosal dimension required for the protection of underlying bone while maintaining tissue health.

Influenza A viruses (IAVs) must navigate through a dense extracellular mucus to infect airway epithelial cells. The mucous layer, composed of glycosylated biopolymers (mucins), presents sialic acid that binds to ligands on the viral envelope and can be irreversibly cleaved by viral enzymes. It was recently discovered that filamentous IAVs exhibit directed persistent motion along their long axis on sialic acid-coated surfaces.

The selection process for Specialty Training Level 3 (ST3) in trauma and orthopaedics is a pivotal yet challenging step for aspiring orthopaedic surgeons. Drawing on personal experience and research, this paper aims to provide a comprehensive analysis of the ST3 selection process, outlining the key stages, including application submission, portfolio evaluation, and interview performance. With recent changes, such as evolving self-assessment scoring criteria and the introduction of a communication station in 2024, candidates face an increasingly dynamic and competitive landscape.

Article Synopsis
- The extraction of a submandibular-displaced mandibular third molar root is challenging for surgeons due to its closeness to important structures like the lingual nerve and sublingual artery.
- Preoperative imaging helps locate the root, but real-time synchronization is tough because of the mandible's moving nature.
- This study highlights the successful extraction of a residual root using a magnetic navigation system, resulting in a minimally invasive procedure with no complications or major issues reported postoperatively.
